Abstract

Current Bioinformatics Challenges in Proteome Dynamics using Heavy Water-based Metabolic Labeling.

Highlights

  • Protein turnover in living systems has been measured with the use of stable isotope labeled tracers for over half a century [1]

  • Since heavy water can be administered in drinking water and does not require iv infusion, proteome dynamics studies can be conducted in free leaving organisms, including humans

  • The key assumptions for the heavy water-based metabolic labeling method are that the labeling of endogenous amino acids is very rapid and there is no post-synthetic labeling of a protein

Summary

Introduction

Protein turnover in living systems has been measured with the use of stable isotope labeled tracers for over half a century [1]. Current Bioinformatics Challenges in Proteome Dynamics using Heavy Water-based Metabolic Labeling One of the drawbacks of the heavy water labeling method is that it cannot be applied to measure the synthesis rates of proteins with the half-life shorter than 1 hour.
